Cirrus Over Water

Originally, this image was going be the cover of my book, but my publisher figured it would be better to use an assortment of images that better suggested what the book was actually about. And, though I do like the cover they came up with (see it in the right margin of this page), I still really like this shot.

So, what is the Cirrus doing flying so low over the water without US Air insignia? I know, because I was there when it was rendered, but I won't tell. ;)
